Hoya 62mm Circular Polarizer HRT

Hoya HRT Circular Polarizing Filters are unique in their design since they incorporate High Rate Transmission film that permits more visible light to be passed through the filters while still producing the same degree of polarized light. These filters now permit the equivalent of 1/3 stop more light to be taken in yet they still filter the same amount of polarized light. This can be a huge benefit to users of both digital and HD technology cameras and lenses. These filters also contain UV properties which aid in eliminating the bluish cast on cloudy days or in open shade.

Light rays which are reflected become polarized. Polarizing filters are used to select which light rays enter your camera lens. They can remove unwanted reflections from non-metallic surfaces such as water or glass and also saturate colours providing better contrast. The effect can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun. Polarizers should be a part of every photographer's gear. They are useful when you wish to increase the saturation of a blue sky or want to make the clouds stand out more. Moreover, they are handy when reflections are a problem - such as when shooting into glass or on the water.

All of this goes into increasing contrast for a more effective photo. The effect of the polarization can be seen through the viewfinder and changed by rotating the filter. The filter factor varies according to how the filter is rotated and its orientation to the sun.

Note! Circular polarizers are specifically designed for use with auto-focus SLR cameras (They will also work on manual systems without problems)

Do I need a filter for a digital SLR camera?

The simple answer to this is yes! Although your images can be edited using imaging programs such as Photoshop, there are some filters that you just can not mimic its results in imaging programs. A suggested type of filter is a UV or Ultra-Violet. While ultraviolet light is invisible to the human eye, it can nevertheless show up on a film image as an undesirable blueish cast; it can even result in a blurring effect. Recommended to be used as a means of protection for the lens (digital slr included), these filters can be left on at all times as it is completely clear and will not change the colour or density of light. Ideal for photography of expansive spaces like mountains and sweeping landscapes.

The second helpful type is a polarizing filter. Reflections of water and other reflective surfaces, like glass, can cause major problems for your images. Polarizing or polarizer filters can fix them because they remove glare from non-metallic surfaces, ensuring a crisp, clear, more colour saturated image. Reflected light can also wash out an image, but polarizing filters combat this nicely by producing deeper colour saturation. Ideal for outdoor photography, a polarizing filter can be rotated for desired effects and the results will produce dramatic blue skies and better contrast and colour.
